Hi!

Yes, you can apply for B.Ed in arts subject if you're a graduate from Arts. In fact one can apply for B.Ed in any arts subject regardless of graduation stream. You only need to graduate with a minimum score of 50%. I hope this will be helpful. All the best!

Hello.
Basically for having any subject in the b.Ed course the minimum eligibility criteria is that the candidate must have cleared his or her bachelor course in arts science or commerce with minimum 50% aggregate from any recognised board or university, so you don't need to bother about that you can definitely have arts subject in b.Ed if you have done your bachelor course in art side.
Best of luck.
